SPECIFICATION forming part of Letters Patent N o. 692,247, dated February 4, 1902.

Application filed May 14, 1901.

To @Zt whom, it itrty concern.-

' Be it known that I, FRANK L. DARWIN, a citizen of the United States, residing at Marquette, in the county of McPherson and State of Kansas, haveinvented certain new and u'seful Improvements in Railway-Switches; and

I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which io itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in stub-shafts and switch-stands, and especially to the provision of means as a substitute for the ordinary frog for making a well-connected track-bearing in either posizo tion of the switch, and the various details of the invention,together with arrangement and combination of parts, will be hereinafter more fully described and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon,form part of this application, and in which drawings- Figure l is a top plan View of a switch, 3o showing switch-rails in place for the maintrack use. Fig. 2 is a similar View showing the switch open or in position for siding purposesA Fig. 3 is a detail view of a bed-plate, on which a switch-point rests and swings. Fig. 3 is an edgeview of the plate shownin Fig. 3. Fig. 3b is a detail view of one of the switch-points.

Fig. 3c is an edge view of the switch-point shown in Fig. 3b. Fig. 4 is a vertical crosssection of the stub-rails, with the switch-stand io and connecting parts shown in elevation. Fig. 5 is a vertical sectional View of the mechL anism for throwing simultaneously connected parts of the switch. Fig. 5a is a sectional View horizontally through the mechanism illustrated in Fig. 5. Fig. 6 is a plan view showing the arrangement of parts when thrown to form a crossover. Fig. 6 is an ele- Serial No. 60,181. (No model.)

vation ofthe construction shown in Fig. G, a portion being shown in cross-section. Fig. 7 is a top plan View ot' the modified form of crossover. Fig. 7 is a vertical sectional View showingin elevation the parts illustrated in Fig. 7. Fig. Sis a View showing in elevation the switch-stand, with parts shown in vertical section. Fig. 8 is a similar view taken ata slightly-different angle,parts being shown in section; and Fig. 9 is a sectional View horizontally through the switch-throwing rod.

Reference now being had to the details of the drawings byletter, A and A designate the rails of the main track, and B and B' t-he rails of the switch-tracks,which are diagonally disposed with reference to the main tracks, one of which, B', is disposed between the tracks A and A'. In the line of the main-track rails are spiked two plates C and C', which are similar in construction and have respectively raised rail-like projections D and D', which are fastened in alinement with the rails A and A'. The other ends of the plates have similar raised rail portions E and E' and F and FQ respectively, which are in line with the main and side track rails. Between the raised rail projections E, F, and D at one end of the plate C is disposed a stub-rail G,while between the raised rail projections F', E, and D is a stub switch rail G. These stub switch-rails G and G are held in parallel relation by means of the bridle-rods H, I, J, and K, which slide in grooves h, zij, and kin the plates C and O'. The bridle-rods are bolted fast, as at M, to the anges L and L on the stub switch-rails G and G'. Mounted on the plates H are the stops o. and h, which serve to limit the throw of the switch-points G and Gr in one direction or theother as they are brought into contact with one edge or the other of the plates C and C.

Referring to Fig. 4 of the drawings, means for locking the switch closed is illustrated, comprising a spring-actuated bolt N, which passes through an aperture in the plate or rail C and its free end engaging in a recess in the under face of the stub switch rail G.

This bolt is mounted in a yoke P, fastened to the bottom of said plate C, and a spring O, bearing between said yoke and a collar on the bolt N, serves to hold the latter normally in a locked position. Pivotally connected to the lower end of said bolt is an angle-lever Q, which is pivoted to the Stringer or tie R at its angled portion, said lever Q in turn being pivoted to the rod S, which is pivoted at one end of the angle-lever T,which is also pivoted at its angle portion to the tie R. One arm of said leverT is projected outward and forms a foot-tread, which when depressed will cause the spring-actuated bolt to be withdrawn from its engagement with the under surface of the stub switch-point G.

The switch-stand N is mounted upon the tie R and has secured thereto a casingV, which isV fastened horizontally to the upper part of the stand, with its center projecting beyond the edge of the tie R, and is centrally apertured to'receive the vertical switch-rod WV. Keyed to said switch-rod is a hand operatingwheel Y, also a lever X, which is keyed to rotate with said rod. In the bifurcated end of said lever is pivoted an operating-handle Z, which is adapted to swing into one of the notches c or d in said casing when the switch is closed or open. This handle may be held clear of the casing bymeans ofa spring-catch @,which is mounted on said hand-wheel Yand comprises two spring-arms, between which the handle is frictionally held above -the casing when swung between said arms, in which position it will not interfere with the rotation of the switch-rod. This casing is made up of two plates, the bottom one of which contains the locking parts,suitably positioned therein, and a top plate or thin covering, incasing the locked parts. Vhen the handle Z is turned down in the stub-notch C, which is the position in which the switch is closed, a hasp A2, which is hinged to a pin on the circumference of the casing, is swung acrosssaid notch, confining said handle therein. rlhis hasp has at its end a hook g, which is adapted to engage the spring-actuated bolt Z, which is mounted in a block B2, which is seated in said casing, said bolt being held at its farthest outward throw by means of a spring and in position to receive the catch .s when the hasp is in the position illustrated in Eig. 9 of the drawings. This spring-actuated bolt may be withdrawn by means of a key of any suitable construction, which may be inserted in the casing for the purpose of engaging the projecting portion of the bolt, so as to withdraw it out of the path of the catch carried by the latch A2. When the latch is released, a spring m, Which is mounted within the casing, will throw the hasp outward, allowing the handle Z to be removed from the notch c.

To limit the throw of the lever X, projecting lugs p and p are provided, against which the handle is adapted to strike to limit its movement in opposite directions, accordingly as it is desired to throw the switch open or closed. The bottom plate of the casing is secured fast to the top of the stand U by four cap-screws n, n, n,an d1t, having sucient space coredy out to leave the heads below the cover-plate, which is in turn fastened to the bottom plate with four flat-head machine-screws o,- o, 0, and 0.

Secured to the switch-rod at any suitable location is an arm C2, to the end of which is pivoted one end of the bar D2, the other end of which bar is pivoted to the bar H. As the switch rod is rocked or rotated the stub switch-rails G and G may be thrown into the two different switch positions. The rod W passes through the bearing E2, which is a part of the base-standard U, also through another bearing F2, which is a part of the cover G2 of the box H2. Both these bearings have removable caps, and the cover G2 has a iiange q, (shown in Fig. S of the drawings,),which is bolted securely to the tie R, while the base I2 of the box H2 may be bolted or otherwise securely fastened to the cover G2. The end of the rod W is mounted in a bearing in a boss fr of the base l2. Secured to the switch-rod V at a suitable location within the box H2 and at right angles tothe arm C2 is an arm J2, to the end of which is pivoted one end of the short bar K2, the other end of which is pivoted to one end of the half-turnbuckle L2, and the threaded end of the rod N2 engages said turnbuckle and is held therein by means of a threaded uut M2. The rod N2 slides in a pipe O2, which is fitted in the boX H2, thus keeping the mechanism completely housed from dirt and Water. The opposite end of the pipe O2 is tted within a similarlyconstructed box H2, in which the opposite end of the rod N2 slides and which is threaded in one end of the halfturnbuckle L3 and clamped with nut M2, the other end of the turnbuckle L2 being pivoted to one end of the short bar K2, which in turn is pivoted to the end of the arm J2, secured to the verticallysecured stub-shaft W2. The lower end of the stub-shaft W2 is journaled in a bearing contained in the bottom part 13 of the box H2, the other end having a bearing in the plate P2, Whichis secured to the top of the ties Q2 and Q2. (Shown in Fig. 5 of the drawings.)

The stub-shaft 72 has secured to it at a suitable location at right angles to the arm J3 an arm C2, the end of which is pivoted in the bar D2, which in turn is pivoted to the flange of the short point R2, Fig. 6 of the drawings, which point R2 is pivoted to the siding-rail B', which has a space cut out for the rod D3 to work in, this plate being passed under the main rail A and spiked, with the rails, to the ties.

Y2, Fig. 6, cut away parallel to the side of the rail B and wide enough to allow the tiange of a wheel to pass through when the pointed rail R2 is thrown against the main track at A. The adjacent rail of the siding on the ou tside The main rail A has a part of the ball` IOO IIO

IZO

of the main track is pointed and bolted fast to the main rail A and held in proper angle yby the block U2, Fig. G of the drawings.

In Figs. 7 and 7 I have shown a slight modification in the construction of the crossover. It consists of the plate V2, which has raised rail-like projections, which are part-s of and are in line with their respective track and siding rails. The raised projection s is made up ofthe junction of the raised projection t, which is bolted with standard anglebars to the main-track rail A, and the raised projection u, which is bolted to the adjacent rail B of the siding outside of the main tracks. The projection t is in line with the projection t and is bolted to the main-track rail A, and the raised projection u', which is in line with the raised projection n, is bolted to the end of the part of the siding-rail B lying diagonally between the main -track rails. At the concaved end of the projection s is pivoted a piece X2, which has a lug projecting down through an aperture in the shouldered end of the projection s and held thereto by means of a key y. Lugs and 'U' are provided to limit the outward throw of the point X2 in opposite directions, accordingly as the switch is open or closed, and a spring which is carried by a lug tu on the plate V2, tends normally 'to hold the point X2 in alinemeut with the main-track rails.

Having thus described my invention, whatI claim to be new, and desire to secure by Letters Patent, is-

l. A switch mechanism, comprising the main and siding tracks, plates and stub switch-points mounted on the latter, bars connecting said points, stops mounted on one of said bars and adapted to limit the throw of said switch-points, combined with a switchstand, a vertically-mounted rotatable switchrod, pivotal link-and-lever connections between said rod and the bar carrying said stops, a spring-actuated bolt engaging one of said switch-points, and a foot-lever and connections with said bolt, as set forth.
